Limited Warranty This Garmin product is warranted to be free from defects in materials or workmanship for two years from the date of purchase. For WAAS upgrade of this product, the warranty is separate and described in the service record or statement.
2. INSTALLATION OVERVIEW Introduction Always follow acceptable avionics installation practices per AC 43.13-1B, AC 43.13-2A, or later FAA approved revisions of these documents. The GPS/WAAS installation instructions have been prepared to meet the guidance material contained in AC 20-138A “Airworthiness Approval of Global Navigation Satellite System (GNSS) Equipment”.
2.2.3 IFR VOR/LOC/GS Installation The minimum GNS 430W installation requires the following items for an IFR VOR/LOC/GS Installation: • GNS 430W (installed in the aircraft manufacturer approved location) • GPS antenna, VOR/LOC antenna, glideslope antenna, and COM antenna. • An External CDI/HSI indicator must be installed in the pilot’s primary field-of-view (or in the aircraft manufacturer approved mounting location).
400W Series unit STC. For mounting the GPS/WAAS antenna, refer to Garmin GA Antenna AML STC SA01695SE or other FAA approved data. For mounting the COM, NAV, and Glideslope antennas, refer to the aircraft manufacturer’s data.
TSO authorized and has been tested to meet Garmin’s minimum performance standards. The GPS antenna should be mounted no closer than two feet from any antennas emitting more than 25 watts of power.
Page 36
Locate the 400W Series unit as far as possible from all COM antennas. If a COM antenna is found to be the problem, a 1.57542 GHz notch filter (Garmin P/N 330-00067-00) may be installed in the VHF COM coax, as close to the COM as possible. This filter is not required for the GNC 420W and GNS 430W transmitters.
Mounting Considerations The 400W Series unit is designed to mount in the avionics stack in the aircraft instrument panel within view and reach of the pilot. The primary unit location should minimize pilot head movement when transitioning between looking outside of the cockpit and viewing/operating the 400W Series unit. The location should be such that the 400W Series unit is not blocked by the glare shield on top, or by the throttles, control yoke, etc.

When valid information is present (Flag OUT OF VIEW) the Flag output is 375 ±80 mVDC.
RMI/OBI 4.9.1 RMI/OBI Function The MAIN OBI output provides bearing information from the active waypoint for Bendix/King Serial OBI devices based upon the 400W Series unit’s GPS navigation. For the GNS 430W, the MAIN OBI output may be configured so that it sends VOR/ILS bearing information when VLOC is selected by the GNS 430W CDI key.
4.10 DME Tuning (GNS 430W Only) 4.10.1 DME Tuning Function The GNS 430W can channel a DME based on the tuned VLOC frequency. The GNS 430W outputs 2 of 5, BCD or Slip parallel DME and King Serial DME channeling format. When DME COMMON is held low, the GNS 430W actively tunes the DME.
4.10.3 DME Tuning Configuration Refer to Section 5.3.14 for the DME tuning configuration. 4.10.4 DME Tuning Calibration and Checkout None. 4.10.5 DME Tuning Interconnect References Refer to Appendix H for interconnect information. NOTE For the GNS 430W to tune a Narco DME 890 or IDME 891 or an ARC (Cessna) RTA-476A using parallel 2 of 5, unique wiring and configuration are required.

Page 115
NOTE The following sections only verify the correct interface of GDL 69/69A to the GNS 400W Series unit. It does not activate the GDL 69 XM data link radio. Complete instructions for activating the XM data link radio can be found in document 190-00355-04.
5.5.6.11.1 Main OBI Output If the Main OBI output from the GNS 400W Series unit is connected to an RMI navigation indicator verify the interface as follows: 1. Apply power to the equipment and wait for the GNS 400W Series unit to acquire a position. 2.
5.6 Flight Checks All system functions that cannot be adequately tested on the ground will require a flight test. Even if all functions can be verified on the ground, a flight test is recommended as final installation verification. Verify system operation as described in the following sections. NOTE The analog deviation (LEFT/RIGHT and UP/DOWN), TO/FROM, and FLAG (lateral and vertical) outputs to a CDI or HSI should be verified in flight with potential sources...
5.6.4 ILS Flight Check (GNS 430W) 1. Tune an ILS at the local airport. 2. Verify the audio ident and audio quality and verify that no objectionable electrical interference such as magneto noise is present. 3. Verify the Morse code decoder IDs the station (95% probability). 4.
5.8 Airplane Flight Manual Supplement Checks Ensure that the Airplane Flight Manual Supplement (AFMS) is completed and inserted in the Airplane Flight Manual (AFM) or Pilot’s Operating Handbook (POH). 1. Fill in the required airplane information in the AFMS. 2. Fill in the appropriate checkbox in the Limitations section of the AFMS corresponding to the type of GPS antenna that was installed.
